Parachute Deployment Device

APP has participated in an ESA Technology Research Programme (TRP) for development of a European Parachute Deployment Device (PDD) for ejection of the parachute of a space probe descent system.

A mortar and gas generator have been designed and manufactured. Analysis of the propellant and full PDD performance was performed by TNO and Vorticity. Detailed design, assembly and integration of all the hardware has been performed by APP.

Tank tests of the gas generator have been performed at APP firing test facilities. Deployment tests have been performed at TNO test facilities in Rijswijk-The Netherlands. The setup includes high-speed camera for determination of ejection velocities and a catching net for the ejected parts. Pressure, temperature and load cells are mounted for monitoring of performance parameters.
